-shipping containers: self contained, easily move anywhere in the world, between ships, trains, rail.
-Can show containers on their own, containers moving between modes of transport, or containers holding a wide variety of materials
-gantry cranes: the things that move modern containers (and kind of look like animals)
-Russian Nesting Dolls (matryuskas): containers inside of containers
-tessellations: simple images that interact consistently to form something interesting
-a gantry crane altered to look like an animal see http://vimeo.com/80543
-interlocking toys (e.g. quercetti octopi)
-waterbears (tardigrade)—small, tough, self contained, can work/survive in almost any environment
Should fit with the general open source aesthetic—friendly, fun, playful, colorful. Should be something that a developer would want to wear on a t-shirt.
Given the prevalence of animal (hadoop, python, mysql, hive, SUSE, Mozilla, go, firefox, linux, PERL) and abstract human (drupal, basho, red hat) logos in Open Source, this may be an area to explore.
Should not look too corporate. Should not look like IBM, NetApp, Microsoft, VMWare, etc.
The goal for open source docker is to appeal to developers, devops types.
